VALID 062059Z - 062200Z THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 579 CONTINUES. MID AFTERNOON SURFACE ANALYSIS SHOWED A BOUNDARY EXTENDING FROM SERN VA SWWD THROUGH CENTRAL NC INTO THE SC PIEDMONT...AND THEN WNWWD THROUGH NRN GA TO FAR NRN AL TO NERN MS. REGIONAL RADAR IMAGERY INDICATED THAT MOST OF THE TSTM ACTIVITY HAS REMAINED CONFINED TO THE VICINITY OF THIS BOUNDARY AND WITH ACTIVITY THAT HAD DEVELOPED AND MOVED E/SEWD OFF THE HIGHER TERRAIN IN THE NWRN EXTENT OF WW 579. CONVECTIVE OUTFLOW INTERACTIONS WILL ALSO AID IN NEW TSTM DEVELOPMENT AS THE AIR MASS ALONG AND S OF THE PRIMARY FRONTAL ZONE IS MODERATELY-VERY STRONGLY UNSTABLE /MLCAPE 2000-2500+ J PER KG/. STRONG WIND GUSTS WILL REMAIN THE PRIMARY THREAT THROUGH THE REST OF THE AFTERNOON INTO THE EARLY EVENING GIVEN THE HIGH MOISTURE CONTENT AIR MASS RESULTING IN WATER LOADING OF DOWNDRAFTS. ALSO...ANY COLD POOL DEVELOPMENT /E.G.
